TRANSMETTEUR SPEEDLIGHT ST-E3-RT

Rented this to pair with my 5D Mark IV and the high-speed sync worked flawlessly for outdoor portraits in bright sun. It triggered three off-camera flashes with zero delay, way better than optical slaves I’ve used before.

Rented this for a wedding job and the high-speed sync worked flawlessly with my Canon flash, even in bright daylight. Controlled three off-camera flashes from across the room with zero lag. Came back clean, no issues.

Rented this for a weekend shoot and triggering fifteen flashes from one spot saved me so much setup time. The high-speed sync held up perfectly even in harsh afternoon sun, no misfires all day.
